I'm trying to find a Ti or alau. cog lockring for my 11/21 cassette. Somebody must make these. You can get a ti lockring for 12/13 smallest cog, but then the cassette goes to 25 and has a bunch of other issues.
Anyone know of a Ti or Alau. Campy 11 tooth cog lockring?

Cyco, The people at the site you gave me didn't respond. No big deal. I have a Ti lockring for 12 t cog and up that I'm going to reduce in dia. on a little lathe I have in the shop. I just spin it on the lathe then grind on things to get the shape I want with a dremel tool. The threads and the splines are allready on the part and they would be hard for me to make. So I think just reducing the lip should do it. Thanks for the site reference.

They responded! I'm going to get one through my LBS. Tiso makes them. Thanks again Cyco.
